Given numbers are 655, 140, 256, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 140) = 18340
GCD(655, 140) = ( 655 x 140 ) / 18340
= 655 / 140
= 655
Step2:
LCM(5, 256) = 1280
GCD(5, 256) = ( 5 x 256 ) / 1280
= 5 / 256
= 5
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 655, 140, 256, 905 is 1
